Taking an ISO image of a working linux machine

Does anyone know how to take an ISO image of a complete working machine (Mint) that I can then use to install a "working" copy on VPS or (in this case) Hyper-V?

The actual scenario is: I have a local backup mail server running postfix/dovecot under Mint. It has a lot of the setup I would need to install on the new Hyper-V server (changes would need to be made but it would be a big saving).

Obviously, the image would be uploaded to the server as a file rather than run from a DVD.

I've seen several responses online to this kind of question but so far they seem too complex to manage easily, too simple (eg not a full image) or are riddled with problems and inconsistencies.

(This is part of my posting [webmasterworld.com...] in the MS forum.)

Kinda all thread but worth updating, take a look at my thread around here: www.webmasterworld.com/linux/4667444.htm

It's a bout a full backup solution and inside there is info about Remastersys, this great tool allows you to create a live DVD iso you can run anywhere and install anywhere if you need so. JUST be careful to get internet connection when you create your backup because it will install (and remove) on the fly "ubiquity", if not, you will be able to run the live thing but won't be able to install it.

Thanks. Bit late, though. :)

I now have the new server installed and am making final adjustments.

I'll keep it in mind for future use.

Nice you got it working.

Your friend/enemy might be the dd command. Useful for backups because it copies the disk bit for bit.

Careful though. It is supposed to stand for something like "disk duplicate". Gaining the reputation of the nickname "disk destroyer", it is not for the faint hearted. Be very careful, if you use this method.
